The adidas Ultra Boost 1. 0 “Solar Yellow 2019” is a reissue of an original colorway that released in 2015. The blindingly-good “Solar Yellow” design returned in 2019, much to the delight of Ultra Boost collectors who missed out on its first release or were just ready for a fresh pair. Contrasting black material embedded within the fabric breaks up the look nicely with the model's traditional lacing cage sporting black Three Stripes branding. A black plastic heel clip features two-toned Ultra Boost branding while the Boost midsole offers unparallelled levels of comfort and support. The adidas Ultra Boost 1. 0 “Solar Yellow” 2019 was released on October 3, 2019.
